Patent EP-0487688-A1 (EP)
Inventor: JOST STEVEN R
IPC: H03F3/30
Filed: 1991-06-18
Abstract: Une configuration d'ampli-séparateur réduit simultanément des décalages en tension continue sur le trajet des signaux entre son entrée (20) et sa sortie (50) et maintient une haute impédance d'entrée et une faible impédance de sortie. Selon un mode préféré de réalisation, une haute impédance est atteinte au moyen du couplage du collecteur (204) du transistor (201) d'entrée à une source de courant à haute impédance (210), laquelle est couplée à l'un des rails d'alimentation (22) de l'ampli-séparateur. L'émettteur (206) du transistor d'entrée (201) est couplé à la borne d'entrée et sa base (202) est couplée à la base (212) d'un transistor de sortie bipolaire (211) à polarité analogue, dont l'émetteur (216) est couplé à une borne de sortie (50) et dont le collecteur (214) est couplé à un rail d'alimentation (22). Puisque les deux transistors d'entrée et de sortie ont le même type de polarité ( de sorte qu'ils peuvent être assez bien appariés au cours de la fabrication) et que leurs jonctions émetteur-base sont connectées en opposition entre les bornes d'entrée et de sortie, ils n'impriment effectivement aucune tension continue de décalage d'origine dans l'amplificateur. Afin d'assurer une haute impédance d'entrée quels que soient la charge de sortie et le gain d'étage de sortie, un étage transistor émetteur-suiveur isolant (221) est de préférence couplé entre le collecteur (204) de l'étage transistor d'entrée (201) et la base (212) de l'étage transistor de sortie (211).

Title: Radon removal system.
Inventor: MATSON STEPHEN L
IPC: B01D61/00
Filed: 1991-06-17
Abstract: Method and apparatus are described for removing dissolved radon gas from water for the purpose of reducing the exposure of household occupants to elevated airborne Rn levels, using a radon-permeable membrane at the interface between gaseous and liquid process streams. The membranes are permeable to the passage of radon gas but substantially impermeable to the passage of the bulk phases. Water is passed along one surface of a membrane in a high-surface-area membrane module, while stripping air is passed along the second surface of the membrane. Radon diffuses from the water stream into the stripping air. The membranes allow rapid and efficient mass transfer in compact devices. The stripping air stream is preferably maintained at a pressure substantially below that of the water undergoing treatment and is supplied to the membrane stripping module by a low-pressure fan or by a blower. Hollow-fiber and other high-surface-area (e.g., tubular, flat-sheet, and spiral-wound) membrane modules are suited to the practice of the invention; hollow fibers provide significant advantages in terms of low cost and high packaging density. The water undergoing treatment may be recirculated between the membrane module and a storage tank or accumulator. Membranes suitable for the practice of the present invention may be (i) dense, polymeric membranes of silicone rubber and various of its copolymers (e.g., the block copolymer formed from polydimethylsiloxane and polycarbonate) and (ii) hydrophobic, microporous membranes prepared from such non-wetting polymers as polytetrafluoroethylene (PTFE) and polypropylene (PP). Porous membranes may be either isotropic or asymmetric. Non-porous or "dense" membranes may either be self-supporting or supported. Preferred are "composite" membranes consisting of a dense film residing atop or within a porous support membrane.

Abstract: The visual testing system consists of polarisation spectacles (14) having different polarisation axes with or without quarter-wave foils of the two polarisation lenses in front of the eyes of the person being examined, and a visual testing instrument for generating light having a specific polarisation direction, or specific direction of turning or rotation of the circularly polarising light. The visual testing instrument consists essentially of two polarisation filters (10, 12) and two LCD displays (11, 13) which are arranged in an alternating fashion. This arrangement is capable of influencing the light coming from a light source (8) in such a way that visual signs or parts thereof can be seen in a pin-pointed fashion only by one eye, or else by both eyes. If the represented visual sign is to be varied, an appropriate command is passed to a switching device (21) via a keyboard (22) which controls the two drive circuits (19, 20) of the two LCD displays in a desired way. It is also possible to examine the colour-normality of the person under examination, given appropriate modification of the visual testing instrument. <IMAGE>

Abstract: The present invention relates to a method and a circuit arrangement for economical operation of an island network having renewable energy sources, which supply energy converters, to be precise in such a manner that the converters are loaded in the sequence of their economy. Furthermore, an energy-storage system (42) is filled with a controlled power load (9). A total desired power value from a higher-level frequency regulator Pdes at an addition point (15) is increased by the maximum power requirement of the energy-storage system (42) Pmax,sp., when the total power which can be instantaneously emitted from the units (2, 4) is greater than the instantaneous total power consumption of the loads (60, 61, 62). This increased total desired power value Pdes,inc. is used for the priority-controlled successive full-load connection of the units (2, 4), and once these units have been connected, the remaining residual desired value is used for controlling the energy consumption of the energy-storage system, in that a different value Pred.,2 - Pmax,sp. is formed from the maximum power requirement Pmax,sp. of the energy-storage system and the residual desired value at a comparison point (46) of the system, which difference value is used as a desired power value for controlling the energy consumption. After filling the energy store (63), the value Pmax,sp. is reduced or set to zero, and a reduction in the desired power value of one of the units is subsequently carried out, which units are supplied using renewable energy sources. <IMAGE>
